We discuss the importance of standards whether they are developed by a dominant company, an industry trade association, a professional society, a government or international organization, or they begin as an Internet Request for Comments.

How will this new charger standard effect manufacturers of phones and other portable devices? How will it effect the consumer? How will it effect the environment? Will any individuals or organizations be harmed if this new standard catches on?

We have discussed the birth of image processing with Ivan Sutherland's Sketchpad program in the 1960s. As we see in this video, Sketchpad could draw, rotate, resize, copy and combine images.

Since Sutherland's research, there has been tremendous improvement in hardware technology and innumerable engineering refinements to image processing software.

Software refinements require research and the development of prototypes before they become product features. Consider, for example, the PatchMatch algorithm developed in collaboration between Princeton University and Adobe Systems. Here we see a paper describing the algorithm and some demonstration videos. The paper was presented and the videos shown at an academic engineering conference.

This is typical of engineering refinements to software. A prototype is developed in a research lab and it later becomes a product.

Researchers typically work on things that are too demanding for the technology of the day. Some of the Princeton videos are shown at 5 times actual speed because it takes time to compute the new images. By the time these features are released in Photoshop, hardware will have improved and they will execute rapidly.

Note that Sutherland's work was a pure university effort, but PatchMatch was a joint effort between a university and a company. Many significant advances have come from industrial research labs. Can you find some interesting prototypes and projects at Microsoft Research?
